So i have had this suspicion that my son has been doing something with my dirty panties for some time now. Im not sure what exactly what but i can only imagine. At first I was a little mad, but then I couldn't stop thinking about what it was he was doing. In my mind I could see him sniffing them while masturbating and it would get me hot thinking about how he enjoys my smell. Well last night I got the better of myself and I masturbated in my panties making them really gooey and wet and left them in the bathroom after I got done with the shower. A little later he had went in to use the bathroom and was in there for about 15 minutes. After he came out I went back in to see if my panties have been moved and sure enough found them balled up underneath my clothes( not how I left them). As I undone them I could tell that he had came in them. I was so turned on that I took off the clean fair I had on and put them on and could feel all what is gooey cum all over my pussy. What I really wanted to do next was to go to him and rub my crotch all over his face so that he would know I knew what he did. But instead I masturbated even more while wearing them. When i was done i took them off and left them inside out crotch up on top of my clothes so when he went back in the bathroom he could see them not as he left them. Now i cant stop thinking about grinding my pussy on his face till i cum.
